RZ/G2L LCD controller composed of Frame compression Processor(FCPVD), Video signal processor (VSPD) and Display unit(DU). The output of LCDC is connected to Display parallel interface and MIPI link video interface.
This patch series aims to add basic display support on RZ/G2L SMARC EVK platform. The output from DSI is connected to ADV7535. The DU controller is similar to R-Car as it is connected to VSPD, so most of code is based on R-Car with new CRTC/DRM driver specific to RZ/G2L v3->v4: * Changed compatible name from renesas,du-r9a07g044->renesas,r9a07g044-du * started using same compatible for RZ/G2{L,LC} * Removed rzg2l_du_group.h and struct rzg2l_du_group * Renamed __rzg2l_du_group_start_stop->rzg2l_du_start_stop * Removed rzg2l_du_group_restart * Updated rzg2l_du_crtc_set_display_timing * Removed mode_valid callback. * Updated rzg2l_du_crtc_create() parameters * Updated compatible * Removed RZG2L_DU_MAX_GROUPS V2->v3: * Added new bindings for RZ/G2L DU * Removed indirection and created new DRM driver based on R-Car DU v1->v2: * Based on [1], all references to 'rzg2l_lcdc' replaced with 'rzg2l_du' * Updated commit description for bindings * Removed LCDC references from bindings * Changed clock name from du.0->aclk from bindings * Changed reset name from du.0->du from bindings * Replaced crtc_helper_funcs->rcar_crtc_helper_funcs * Updated macro DRM_RZG2L_LCDC->DRM_RZG2L_DU * Replaced rzg2l-lcdc-drm->rzg2l-du-drm * Added forward declaration for struct reset_control [1] https://patchwork.kernel.org/project/linux-renesas-soc/patch/20220312084205.31462-2-biju.das...@bp.renesas.com/ RFC->v1: * Changed minItems->maxItems for renesas,vsps. * Added RZ/G2L LCDC driver with special handling for CRTC reusing most of RCar DU code * Fixed the comments for num_rpf from rpf's->RPFs/ and vsp->VSP.
